And bottom for employment statistics:
"Northern Ireland has ranked among the bottom two UK nations or regions for employment in all but 12 of the past 115 quarters."
"Prior to the Covid crisis, Northern Ireland set a number of economic records – employment, output, unemployment, export and more,” Johnston said. “However, whilst the region’s performance appeared strong when considered against its own historical context, it remains weaker than competitor nations and regions across the UK, Ireland and Europe.”
Just under half of Northern Ireland's parliamentary constituencies are in the bottom poorest within the UK as well.
Northern Ireland has a higher proportion of households with no savings than Great Britain (45% compared to 33%).

And by poorest part of the UK, this means in comparison to the entirety of England, Scotland and Wales.

All in all, Northern Ireland is poorer than England, Scotland and Wales.
